So, I decided to see how my HX520 would do an overclocked Q6600 system at 3.2GHz, with 4x1GB running at about 850MHz, and a single 7900GS volt modded to 1.55V running at 700/900 clocks.
System powers up, I'm seeing 12.00 on the multimeter exactly. Impressive...
I load up P95 large FTT (for max power consumption), ATI Tool with artifact scanner running, and Windows Media Player just for the hell of the sound card & HDD to be going at the same time.
Here are the software readings (Easy Tune 5 on a P35-DQ6) versus the multimeter.
Software reading | Multimeter Reading
---------------------------------------------
11.92 idle | 12.00 idle
11.79-11.85 load | 11.97-11.98 load
So why is this software reading so off? Does software just "assume" that the 12V will drop when the system is put under heavy load? Is there actually anything built into motherboards that attempt to read the 12V rail?
